Among other strengths, the database includes detailed geographic data on fatal incidents-a feature lacking in other systems that track workplace fatalities. It is clear that the majority of OGE worker fatalities occurred in rural micropolitan and noncore counties (Figure 1). This finding may not be surprising to people in the industry. However, it does raise questions about relationships between work, health, and rurality that are rarely explored explicitly or systematically.The uneven allocation of social and structural determinants of health (SDOH) across geographic space accounts for disparities in health outcomes among people living in urban and rural areas. 3 Employment is an SDOH that can impact health through working conditions, access to income, health insurance, a sense of meaning, and quality housing.
